BOTTLE-CAP REMOVEB.

Specification of Letters Patent.

Application filed March 14, 1917. Serial No-. 154,699.

To all whom it may concern Be it known that I, OSWALD- PnTsoHnL, a citizen of the United States, andv resident of the city of New York, Stapleton, in the borough of Richmond and State of New York, have invented a new and Improved Bottle-Cap Remover, of which the following is a full, clear, and exact description.

This invention relates to bottle stoppers and has particular reference to means for removing or otherwise manipulating bottle stoppers or caps such for example as the thin cardboard paper or analogous stoppers commonly used on milk bottles.

Among the objects of the invention is to provide a simple, cheap and reliable device adapted to be applied directly to a milk bottle cap while in place on the bottle and through which said cap may be withdrawn and subsequently returned to its place if desired, without any danger of wasting or splattering any of the cream or milk.

lVith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a perspective view indicating the stopper end of a milk bottle and my improvement while being directed to ward the stopper for application thereto.

Fig. 2 is a vertical sectional view showing the barb portion of my improvement just after it has been projected through the center of the cap.

Fig. 3 is a plan view of the device after it has been turned through an angle of about 90 degrees from the position of Fig. 2.

Fig. 4 is a perspective view showing the underside of the cap and the relation of the barb of my improvement thereto in the same relative position as in Fig. 3 though with the entire device turned with the cap through 90 degrees.

Fig. 5 is a plan View of the improvement showing how it may be stamped from a single sheet of material, and

Fig. 6 is a perspective view of the improvement alone in the same position as in Fig. 4: but without the cap.

Referring now more particularly to the drawings, I show my improvement as embodying three principal parts or features, namely, a finger piece 10, a pair of wings or guards 11 and an anchor member 12.

As indicated I prefer to stamp or otherwise form all of these parts from a single piece of sheet material such as metal of any suitable species to provide the necessar Y strength and having a sanitary nature. Obviously I do not desire to be. limited to any particular shape or design of the blank or any of the parts formed therefrom and while I show in Fig. 5 the blank as of circular form, it is obvious that other forms might be used. The form shown, however, is well adapted for the purpose of the invention and for economy of metal.

The finger piece 10 is shown as comprising about one half of the blank and the anchor portion is formed about the center of the other half. This anchor is indicated as of dart shape and having a point 12 adapted to facilitate the forcing of the anchor directly downwardly through the center of the disk or cap 0. The anchor is connected at the center of the device to the lower portion of the finger piece by means of a neck 13, the length of which is sufficient to allow the anchor to be forced through the cap and readily turned so as to lock the shoulder portions 14iof the anchor beneath the cap at right angles to the slit 0 formed through the cap by projecting the anchor therethrough The guard or wing members are shown as two in number and are formed by slitting the blank at 15 along the inclined edges of the anchor and at 16 where the ends of the wings coincide opposite the point 12 of the anchor. After the slitting is donewhich is substantially coincidental with the stamping out of the device from the sheet of metal, the wings 11 are both bent around the lines 17 at 90 degrees, to the plane of the finger piece and anchor, but in opposite directions, that is to say considering the finger piece and anchor as lying in their original plane with respect to the sheet of metal, one wing is bent upwardly from said plane and the other is bent downwardly therefrom. The wings in their final position therefore lie in the same plane and perpendicular to the plane of the finger piece and anchor. In practice therefore the wings abut against the upper surface of the cap while the finger piece and anchor lie in the vertical plane perpendicular thereto. It will be noted that the bending lines 17 for the wing lie in the same diameter of the blank, and with the wings formed with are shaped peripheries and bent through 90 degrees from their original position, they in their final position will still describe 90 degree arcs of the same circle. See Fig. 3. Among the purposes for thisparticular clesign of the wing structure is to insure that when the anchor member is being forced directly through the center of the cap, the peripheries of the wings will strike squarely against the outer surface of the cap comparativelyclose to the periphery of the cap or where the cap is seated snugly upon or against the flange Or shoulder 18 of the bottle. This is one of the reasons therefore why there is no immediate danger or likelihood of collapse of the cap or splattering of the milk or cream from the bottle when the device is being applied to the cap.

The rotation of the device around its vertical center or the axis of the point 12 naturally is accompanied with sufiicient friction or resistance from the structure of the cap incident to the slitting thereof byth anchor, to insure that the attachment or remover will always remain in definite position with respect to the cap until the bottle is empty or the device is to be transferred to a subsequent bottle. Obviously therefore with the device applied to the cap as shown herein the can may be drawn directly'from the bottle, the shoulders 14 of the anchor being sufliciently long to prevent the anchor from tearing upwardly through the cap, and after a portion of the milk is poured from the bottle the cap may be returned thereto simply by manipulating the finger piece. The operators fingers therefore need never become soiled or moistened from or by the milk. 7 For this reason and the fact that the cap may always be readily returned to its place to exclude impurities, the device is notonly neat and convenient for use but is of a very sanitary nature.

I claim:

1. The herein described bottle cap remover of a single piece of sheet material of uniform thickness comprising a dart-shaped anchor member having a point to puncture the cap and having also shoulder means to interlock with the cap When the'anchor memher is turned around the vertical axis of said point, a fiat finger piece, a neck connecting the finger piece to the anchor, and a pair of guard wings connected to opposite end portions of the finger piece and lying in a plane perpendicular to the plane of the finger piece to limit the downward movement of the device while the anchor is being forced through the cap, said wings extending laterally in opposite directions from the plane of the finger piece.

2. The herein described blank for a sheet metal bottle cap remover, the same comprising a finger piece portion, an anchor portion spaced from the finger piece, a neck portion connecting the anchor to the finger piece, and a pair of wings constituting guard members lying along the anchor remote from the finger piece and having their free ends abuttingagainst each other.

3. The herein described blank for a sheet metal integral bottle cap remover, the same comprising a disk shaped member one half of which constitutes a finger piece While the other half comprises a central dart shaped anchor having a point remote from the finger piece, nd a pair of wings having ar shaped peripheries bounding the anchor and connected to the finger piece along bending lines lying in the same diameter.
